This is usually caused by Tseng ET4000 chips in the video controller (batch TC6059AF or higher only!). If the customer has these chips in his video board, send the fix for APAR PJ03677. 2) SYS3176 error when starting a DOS session. Try setting HW_ROM_TO_RAM to ON for each session that is having the problem. Also try changing DOS_RMSIZE to 624 instead of 640. If this does not work, the VSVGA.SYS fix from IBM might resolve the problem. 3) ATI 8514 Ultra or Graphics Ultra locks with white screen on bootup. The older ATI ROM chips return an incorrect monitor ID when queried by OS/2. Have customer call ATI at 416-756-0711 to obtain an update. Remember, these boards MUST be set up as an 8514 PRIMARY display and the statement DEVICE= OS2 MDOS VVGA.SYS MUST be changed to DEVICE= OS2 MDOS VSVGA.SYS 4) C0000005 error on bootup. If the customer has Western Digital chips (C30 or C31), with 1MB memory, send the fix for APAR PJ03721. If not, remove the SVGA info from the CONFIG.SYS file. Note that this will limit the user to VGA only. Change SET VIO_VGA=DEVICE(BVHVGA, BVHSVGA) DEVICE=C: OS2 MDOS VSVGA.SYS to SET VIO_VGA=DEVICE(BVHVGA) DEVICE=C: OS2 MDOS VVGA.SYS 5) Trident video problems: If the user is experiencing problems with super VGA on Trident based video boards, they will need to call Trident (not IBM) for the proper SVGA driver. If they have problems with the driver that Trident sends them, they need to call Trident, not IBM. IBM only supports VGA mode on Trident boards with 8900 or 9000 chipsets. The 8800 chipset is not currently supported nor do I believe that it will be. 6) Dell computer Video problems. Dell's 486/50 uses a Western Digital 90C30 chip. Our standard BVCHSVGA.DLL fix should help. Other models (325SX, 325, NL25, etc.) do NOT use this chip and this fix DOES NOT apply. Dell uses a customized Phoenix BIOS. Here are a few CMOS settings that have been known to help. Use CTRL-ALT-ENTER to access CMOS setup: FAST_VIDEO OFF if sync problems FAST_VIDEO_BIOS (shadowing) OFF if problems BIOS_CACHING OFFif problems COMPATIBILITY_SPEED ON for faster Mhz machines 7) Errors loading video drivers on bootup. The selective install utility sometimes will add the same device driver statement more than once to the CONFIG.SYS file. This will result in an error message every time the user boots up. The system will function properly and upon investigation you will find that driver file DOES exist in the proper directory. It is simply trying to load the driver twice during bootup, the second attempt will fail. Remove the duplicate DEVICE= statement from the CONFIG.SYS. LOCAL FIX:
